A new type of turbomolecular vacuum pump bearing

Abstract
It has been found practical to operate a vertical rotor turbomolecular vacuum pump with at least one oil lubricated journal or ‘‘sleeve’’ bearing of ringlike proportions running at film sheer speeds of 87 m/s (194 mile/h). Aside from unlimited life and low noise, the new bearing has heat transfer capabilities which will extend the pump’s useful blowers.
